In July 2011, Air Force Staff Sgt. August O’Neill, a pararescueman, was sent to rescue a group of Marines pinned down in Afghanistan when enemy insurgents opened fire on his team’s helicopter.

A round bounced off the helicopter’s door, tearing through both of O’Neill’s lower legs and critically wounding his left, resulting in 20 surgeries over the next three-and-a-half years as doctors tried to save the limb.

O’Neill finally told doctors to remove his left leg last year, but he remains determined to continue his career as a pararescueman.
